w This invention relates to separable fastener sliders and has for its object toprovide improvements upon the sliders shown in my Patents #1,219,88l, dated March. 20, 1917,

and'# 1,302,'606, dated Mayfi, 1919, wherein are shown sliders. having the actuating "16 --means attached on an-end thereof.

f According to this invention, a rigid pull istransversely pivoted about the center of the slider and preferably to the specially "formed head of the rivet which-holds the I Such a constructionis adapted to. provide a 'smoothtravel for'the slider along the stringers; the actuating force applied at about. the center or intermediate portion and i .85 above the plane of 'thestringers has-an upward component thereof effective to raise the slider instead ofraising only one end 4 thereof, as is'the'case-when the pull is attached at the end. This enables the slider 30. to move more easily andsmoothly when the actuating force is applied at a central point Another advantage accruing from the location of the pull in the centeris the pro-vision of surfaces on either side of the pull, lengthwise of the slider against which theoperators fingers may be pressed tosteady the'movement of' the slider and lessen chatter when the pull is heldbetween the finger s, 'or more precisely the thumb and forefinger.

-.The slider lfl of this invention ,is'adapted to be used for similar purposes tothe slide;

illustrated in my Patents #1,219,881 and #1,'302;606-above referred to wherein the slider controls the engagement of a number of locking members 11 mounted on stringers 12. blank having .win portions 13 connected by the neck 14. [he wing portions have inturned ed es '15 adapted, when bent to the shape il ustrated, to provide diverging .channels through which the locking members pass and to stiffen the wings.- A rivet 16 passes through the wing portions and preventsthem from spreading. Before in- The slider is formed from a metal i sert'ion of the rivet the spacerlportions I7 are bent down. and inserted between the wings to hold them a fixed distance apart When clamped-by the rivet. The lower ends 18 of eah spacer 17 are bent inwardly as shown in Fi 1 to'form inner walls for the,

diverging c annels. .The rivet 16 has a head 19 on one side and aportion 20 on the opposite end adapted to be bent down in clamping ,thewing portions. Grooves 21 in the rivet head provide means for trans verselypivoting the pull device 22 in the intermediate portion of substantially the center part of the sliderso that the operators fingers may steady the surface of the slider longitudinally on each side of the pull device. Within the rivet are guide grooves 23 which form the wedge shaped cross section shown in Fig. 2 with the point of the wedge atthe vertex of the diverging channels. Such' grooves 23 are rounded to provide the necessary clearance for the locking members 11 and may serve to guide the lockmembers.

in v operation, the pull device v22 maybe actuated in the usual manner when the upwardcomponent of a diagonal pull tends to raise the entire slider instead ofonly one end thereof. 'When-the pull is grasped between the thumb and Ifinger, and the thumb.

and finger pressed a ainst the surface of the slider on each side of the pull longi tudinally thereof, the movement of the slider will be smoother since the steadying action of the thumb and finger against the surface of the slider lessens chatter ot' the locking members passing through the channels and lessens any tendency to side twist or jerk.

With the sliders of the patents referred to, difliculty was encountered in finding a suitable location where the statutory patent markings may he placed. were unsuitable because if aliixed in ink such markings became fugitive on washable goods and in many instances could not be seen because the stringers are secured beneath the sides of the slit to be closed by the fastener. The lower or inner face of the slider is open to the objection of being of limited area and not plainly visible for the imprint of the necessary markings. but with a rigid pull device of fiat material of the type shown such markings may be placed on either or both sides thereof.

In Figures 5 and 6 is shown a slider corresponding to that shown in Figs. 1 and 2 except that the rivet head 2-l is more elongated. Grooves 25 permit limited shifting of the point of application of the actuating force in the rivet head.

Figure 7 shows the form of blank stampe from sheet metal and before being bent back on itself to form the slider shown in Figs. 1, 2, 5 or 6.

Among the advantages of. this invention may be enume atedits simplicity and rigidity of construction whereby the slider body and Wings are stamped from a single sheet which also contains the spacer portions 17.

The rivet clam )S the win s a ainst the s ac ers and also prevents spreading of the wings. The rivet is located between the spacers referred to and enables the pull device to be secured in substantially the central part of the slider. This invention provides a rigid slider of minimum overall thickness. wherein the pull will naturally lie flat below the top of the rivet. This permits the slider on washable articles to pass readily through a wringer without dan'iage, and also does not provide objectionable projections on articles equipped with this slider. Securing the pull in about the center of the slider permits a diagonal actuating force to have a component tending to lift the body of the slider instead of only an end thereof to produce smoother travel of the slider. Another teature contributing to smoother travel and resulting from the location of the pull device intermediate the end portions of the 'slider is the provision of the supporting surfaces on each side of the pull longitudinally of the slider whereby the thumb and finger of the operator may rest against.- these supporting surfaces tosteady the travel of the slider and lessen the tendency to jerks and chatter in its n'iovemcnt. The elongated rivet head 24 of Figs. 5 and 6 provides a The stringers very rigid construction for the slider and pull attachment and permits limited travel of the pull relatively to the center of the slider, which will be desirable in largeslidcrs for heavy work. 7

It will thus be seen that the slider of this invention comprises only three parts, the wings, neck. spacer and inturned edges being formed integral, the rivet holding these parts in fixed position and near the center of the slider whereby any tendency of the diverging channels to spread fsreduccdlo a minimum and the attachment of the pull device tothe rivet head completes the slider.

This slider is especially adapted for fasteners attached to purses, bags, tobacco pouches, garments, and others, and is in short applicable to any fastener where it is convenient to hold the pull in such manner that the slider is supported by the fingers to retain its position parallel with the interlocking plane of the fastener. The transverse pivotal attachment of the pull facilitates travel of the slider around corners.
